My question involves vehicle registration or title in the state of: California
Last week I purchased a used vehicle, and at the time of the purchase the owner (a small Chinese girl studying abroad, assumed she was sincere) guaranteed that it would pass smog, and showed me a bill of sale on a transmission replacement one year prior. I had the car checked by a mechanic and he said that there weren't any serious issues with it. So I bought it. We signed all the appropriate forms and what not, and I went on my way.
Then on the way home, the check engine light came on... I took it to my mechanic and he said that the transmission is failing (great), and it apparently only had a 3 month warranty on it. With the Check Engine light on, it won't pass smog.
I called the seller explaining to him the situation and she gave me a hard time then had to go. Then she mostly ignored my requests for contact, and wont let me return the vehicle.
I've put about 100 miles on it, and haven't taken it into the DMV to register it yet because it wont pass smog.
What are my options at this point? Can you show me any relevant laws or regulations to help make her refund me?
